<h2 id="cargo_login_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph">
<p>This command will save the API token to disk so that commands that require
authentication, such as <a href="cargo-publish.html">cargo-publish(1)</a>, will be automatically
authenticated. The token is saved in <code>$CARGO_HOME/credentials</code>. <code>CARGO_HOME</code>
defaults to <code>.cargo</code> in your home directory.</p>
</div>
<div class="paragraph">
<p>If the <em>TOKEN</em> argument is not specified, it will be read from stdin.</p>
</div>
<div class="paragraph">
<p>The API token for crates.io may be retrieved from <a href="https://crates.io/me" class="bare">https://crates.io/me</a>.</p>
</div>
<div class="paragraph">
<p>Take care to keep the token secret, it should not be shared with anyone else.</p>
